35mm polystyrene balls.
These balls are of a lower density polystyrene than the others in our range, hence there is a difference in the price by comparison.
Best cut with a fine-toothed tool as a knife may cause the cells to break away.
Cover with coating products (see below) if a textured surface is desired.
Polystyrene will melt if subjected to any solvent, so take care with paint, if used (especially aerosols, as the solvent may be in the propellant).
Most of the ‘Do-it’ and ‘Belton’ paints are suitable. Always test a piece before applying to your finished work.
The same caution is required for any adhesive used.
Our recommended adhesives are listed below.
